- further objects are to enable the form rolls to be removed without thenecessity of removany coacting roll from the press; to permit theseveral ink-rolls and drums to be readily viewed from one side of thepress; and to enable the ink to be worked up or thoroughly mixed on allthe rolls save the form-rolls, avoiding allaccumulation on the latter. 4

The invention will be hereinafter fully set forth and particularlypointed out in the claims. i

In the accompanying drawings, Figure 1 is.

a diagrammatic end view, partly in section. 2 is an end view with thetransfer rolls out of engagement with the form-rolls. Fig. 3is an endview looking in the direction opposite to Figs. 1 and 2; Fig. 4 is arear elevation, with parts broken away. Fig. 5 is a fragmentary rearelevation on an'enlarged sea e.

Referring to the drawings, 1, 1, designate two ink drums whose shafts 2are journaled at their ends in the sides of main frame 3, (see Fig. 4)such shafts being capable of moving longitudinally in their bearings 4in shifting the drums back and forth; On each shaft 2 is a gear wheel 5,both of which mesh with, and

are driven by, an intermediate gear wheel 6 leather covered rolls 13,and from the drums it is transferred to the transfer rolls 7 byintermediate transfer rolls 14. These transfer rolls 14 have theirbearings in hangers 15' hung from bearings 4 of shafts 2, concentricallywith drums 1,' while the bearin s of the transfer rolls 7 are mounted onshafts f 16 which extend through the frame, and carry arms 17, connectedby links 18 to the arms of crank shafts 1Q havin manipulating handles20. By depressing t e latter, the transfer rolls 7 can be swung up andheld away from the series of form rolls 21, the transfer rolls 14 movingwith them since they rest upon said rolls The shafts 19 carry arms 22having laterally projectin pins 23 which contact with the edges of t eframe to limit the swin of the transfer rolls 7 both into and out of teir normal positions. The frame at the front is overhung, and has aplate or projection 23* with which the pin 23 of the arm of the frontshaft 19 contacts when the rolls 7 are elevated. The toggles formed bylinks 18 are slightly broken when these rolls are heldout of engagementwith the form rolls, as shown in Fig. 2. By the described construction,when the transfer rolls are thrown out of engagement with the formrolls, ink may be thoroughly Worked, or mixed with an oil or otherreducin agent, Without the necessity of removing t e form rolls from thepress. These form rolls are shown as arran ed on an arc of a circleabove the form cylin er 1 beneath which (see Fig. 1) are the transfercylinder 1 and the impression cylinder 1 The stop pins 23 by engagingwith the frame when the handles 20are thrown. up, as shown in Figs. 1and 3, prevent the gears of the rolls 7 meshing too dee in the co-actingrears, and

likewise avoid al tendency of such rolls to crowd against the formrolls.

The ink drum-shafts 2 carry'gear pinions 24 fixed thereon betweencollars 25 held on such shafts by nuts 26. These ear pinions 24 meshwith a gear wheel 27 in t e form of a shifting cam journaled in anoverhanging arm or bracket 28, such gear being driven by said pinions24. On the shafts 8 of the two transfer rolls are gear pinions 29located be tween collars 30, such pinions and collars being pressed uponsleeves which turn loosely on said shafts. These pinions 29 mesh withand are driven b ear Wheel 27.' The col lars 30 engage bal earings 31held place by collars 32, the urpose being to minlmize the frictioncause by the difference in speed between the gear pinions 29 and theirrespective shafts 8, said inions revolvin at the same face speed as t eperiphery of t e shifting gear 27. The rotation of the latter effectsthe lon itudinal'shifting or reciprocation of the drums 1 and thetransfer rolls 7, the shifting of all being effected simultaneously, thedrum of one series and the transfer roll of the other series alwaystraveling in opg osite directions.

he shifting gear 27, and the ear pinions of the ink drums and the transer rolls are located at the same side of the press as are the gears forrotating the ink drums and transfer rolls. In consequence the other endof the frame may be left open, and permit of ready and easy inspectionas well as access for the removal of foreign substances without thenecessity of removing the rolls from the frame.

By the means described the. thorough working of the ink is accom lishedthrough two serles of rolls and drums efore it reaches, Not only is theink trans-' the form rolls. ferred to two drums whereon it is thoroughlydistributed by se arate sets of rolls, but these drums are einconstantly reciprocated longitudinally w ile revolving, as are also thetwo transfer rolls by which the ink is distributed to the form rolls.This is of spec 1al advantage in planographic rintmg where the ink mustbe well worked efore it is applied to the plate on the form cylinder.When the transfer-rolls are elevated from the formrolls, any one or allof the latter may be removed by bein moved upwardly from their bearingswit out the necessity of removing any other roll, Another advantageresulting from the described arrangement is that the means for shiftinand rotating the ink-drums and transfer rol s being located at one sideof the press, the supporting frame may be of skeleton formation at theother side, thus leaving a clear opening through which the several rollsmay be inspected from time to time to ascertain the conditions thereof,and to locate and, insome instances, remove foreign substances, such aspieces of We claim as our invention: 1.
